2020 GMC Sierra 3500 SLT review
Great Diesel truck when emission sensors work
Great vehicle for pulling my fifth wheel RV which weighs around 20,000 pounds. This dually truck pulls the RV very nicely without any significant strain on the engine or the transmission. However, like all of today's diesel engines there are 4 different system of emissions on this truck. Each one of these emission systems has sensors associated with them. If one of these sensors goes bad the truck will not perform optimally and sometimes it will go into the limp mode. Unfortunately this is not unique to GMC trucks. All manufacturers are battling this system. Also, I have had to take the truck to the dealer for computer upgrades in order to improve performance. I wish these upgrades could be performed on line (through wifi or with my own phone service). It sure would make things a lot simpler and improve the through put of the dealers who are already strained because of the limited number of available diesel mechanics.

Great selection of high end quality vehicles. Would definitely recommend to anyone in need of a luxury vehicle
2020 GMC Sierra 3500 SLT review
Great luxury ride with great pulling capabilities.
The Texas Edition combined with the X31 package and premium SLT makes a very nice combination. The Sierra 3500HD gives you a luxury interior and ride with all the capabilities of a great pulling truck. The Duramax is quiet yet powerful. It is no doubt the best of trucks for 2020.

Frank Boucher VW Kia of Racine review
Having recently purchased a 2024 Kia Seltos at this
Having recently purchased a 2024 Kia Seltos at this dealership, I can relay that it was a pleasant experience. Kyle Miller knew his inventory and found just what I was looking for, after listening to me. Every effort was made by him and other personnel to assure that I was comfortable and that details were explained to me. There were no high pressure tactics used. Even after my first choice car got sold the evening prior, I was shown a similar vehicle with most of the same features, and at a lower price point.

Max Curnow is the only place I get my vehicles serviced!
Max Curnow is the only place I get my vehicles serviced! Mainly because of the customer service I receive from Shawn and Kolton! Those guys are extraordinary at their job! They make sure you are fairly taken care of! Every time I go in to talk with them. They are always busy with customers or handling phone calls etc. However, they still are able managr and juggle their tasks with poise! Will definitely return because of them!
